"I went home and I just couldn't get it out of my head", said Dawn Caviola, a regular of Donut City for the past 13 years. "We need more people like that to just help everybody out in whatever need they have". Customers also offered to set up a GoFundMe page to help the couple but Chhan reportedly declined the offer because he simply wanted to spend time with his wife.

"Come and support this guy's donuts", one customer said, KCBS reported.

Customers launched a heartwarming campaign to purchase the shop's entire doughnut stock every morning, after learning Mr Chhan would visit his wife at the rehabilitation centre after selling all his doughnuts and cleaning the shop.

Others are helping spread the word via newsletters and by word of mouth, convincing everyone to buy doughnuts one dozen at a time.
